So, Starraid (FulliAutomatix) and I bring you: RUKTS
A UK train set in 2cc designed for playability rather than realism with a variety of features including...
2cc (or not, through a parameter)
Selectable liveries (or not, through a parameter)
Variable length EMUs and DMUs
A pacer
Functioning driving trailers
Other things

Also available is "RUKTS - Extension" GRF which will contain additional graphics to go with the main GRF that aren't UK rail vehicles.
Currently available in the extension GRF:
Nuclear cargo chain - Uranium Mine -> (Uranium) -> Power Station -> (Nuclear Waste) -> Nuclear Reprocessing Site.

Any chance that a Class 317 EMU could be added to the future plans for this set? In this and other historically realistic UK sets, there is a lack of a fast overhead electrification/AC EMU before the 1990s. The 317 was introduced in the early 1980s and has 100mph capability, and so it would be good to have a fast EMU available in that era for the game.

Funny you should mention those EMUs...
We've got a 319 near enough ready for coding, a 321 on its way and a half finished 309! Hopefully these should all come in the next update. The 455 was created with the 317 in mind, so that wouldn't be too hard either.
